Application filed June 27, 1924, Serial No. 722,838, and in Germany June 2'7, 1923.

My invention relates to a machine for sorting corny or granular substances or materials, more especially corn or grain. and the like, according to the weight, the shape,

and the quality of the respective substance or material; the chief object of my invention in the case of corn or grain is to obtain an unobjectionable seed-corn or seed-grain, and

I attain the object in View by certain. ar rangements and combinations of parts, as

described hereafter.

I am aware of certain known sorting machines in which a casing or box enclosing the operating parts is supported on archshaped segments and the reciprocating or rocking motion is effected either by connecting rod or by connecting rods, or by a link or by links engaging a reciprocating or rocking table at one of its ends. In. con tradistinction to that manner of supporting and rocking the casing or box together with the operating parts enclosed therein, all these parts are suspended in. my improved machine from pendulums and are rocked by two links or crank-guides attached to the long sides of a main-plate carrying the operating parts.

The sorting-table with its bathe-members is combined with a feeding device located above it and serving also as a pre-sorting device in which the corny or granular substance or material is pre-sorted in such a manner that all parts of the table receive equal amounts of equal weight.

The table can beadjusted obliquely in various positions at right angles to the direction of the rocking motion. The degree of the obliquity depends upon' the kind and quality of the substance or material to be treated. and the means for adjusting the table obliquely and for securing it in its ad.- justed position consist, among other parts, chiefly of a rotatory eccentric combined with a nut-forming hand-wheel, as is all fully described hereinafter.

My invention is illustrated by way of ex ample in the accompanying drawings, in which Figure 1. is chiefly a side-view of the machine, and partly (top of box or casing) a vertical longitudinal section thereof; Figure 2 partly a frontal view and partly a cross section in. line C-D-EF--G-H of Fig. 1; Fig. 3 shows some details drawn to an en larged scale and in vertical section (plane JK of Fig. 2) and Fig. l is a horizontal section-through the feeding and pre-sorting device located in the top of the box or casing (section-plane: L-M of Figs. 1 and 2.) Fig. 5 is a horizontal section through the sorting table (section-plane: QR of Fig.

On the drawings (Figs. 1 and 2) 1 denotes four vertical standards secured to a foundation; they are connected with each other in pairs by strut-rods 1, and from each stand ard is suspended apendulum-rod 2 by means of a bolt 3. The bolts are adjustable vertically in the tops of the standards by means of threaded spindles 4t and can be secured in their adjusted position by nuts 5.

Between the four standards 1 a horizontal plate 8 is arranged furnished with four oblique feet 6 connected with the free ends of the pendulums 2 by bolts 7. To the plate 8 are secured two cross-beams 9 9, and to each thereof is aiiixed, a bearing 10 or 10 respectively. located in the middle of the respective cross-beam. The two bearings support a horizontal shaft 11 which carries the sorting table 12 on which bathe-members are pro vided 12 (see Fig. 5) constituting channels 12 on the surface of the sorting table 12 in known manner.

From the bottom of the plate 8 two crank guides 13 and. 13 located at the long sides of the plate and in the middle of each side extend downward and in each of these guides a slide-block 14, or 14 respectively is located which is engaged by the pin of a crank 15. or 15 respectively. The two cranks are affixed to a horizontal shaft 16 supported in bearings 16 and. 16 and provided with a conical driving drum 17. A. similar drum 18 is arranged in inverted position parallelly to the drum 17 on a suitably located and supported driving shaft, and the power is transmitted from this latter drum to that other one by means of a belt 19 which can be shifted along the two drums in known manner so as to vary the speed in certain limits. I

At one end of the cross beam 9 a guide i with a hand-lever 25, whereas the projecting end 26 of the axle 23 is threaded and is provided with a hand-wheel 27,- the hub of which is threadedinternally so as to form a kind of nut.

Another such arrangement and combination of parts as described in the preceding paragraph may be provided also on one end 1;. all

of the other cross-beam, and the axle 23 passes then from one frontal face the table to the other frontal face'but instead of an axle like 23 two separate journals may be provided at the two frontal sides of the machine, as will be clear without entering into, the details of this modification.

.lVhile the device dealt with in the. last two paragraphs is intended for varying the obliquity of the table, another device intended for securing the table in its adjusted position is provided at the opposite end of the cross-beam, or of each cross-beam (9 and 9) this deviceconsists of a vertical guidemember 28 fixed to the respective cross-beam and of a journal 29 secured in the respective frontal face of the table and having a threaded end bearing a nut-forming handwheel 80. y

From each cross-beam (9. and 9) a rigid vertical member or support3l, or 31 respectively extends upwards, and; the two memrs or supports carry an oblong box 32 containing the parts eliccting the pro-sorting and the uniform. feeding of the respective substarwc or material to the table 12. The box 32 is open, save two narrow cross-plates located at its ends, and below the open top, within the box, a horizontal plate 34 provided with crosswise arranged bathe-ledges 3 and 35" is provided; these ledges are practically triangular in cross-section andso arranged as regards. the oblique side of each that this side is directed towards the middle of the plate 34. Thus, in. Fig, l the oblique side oii the ledges 35. is on the left and the oblique sideof the ledges 35 is on theright. The object of these ledges is to, facilitate the transport of the grains from the middle part of the plate 34 to the two endsthereof.

Above this plate movable oblique plates '36-and' 36 are provided which are turned or swung upwardsv automatically, or are lifted automatically, by the-rocking motion of the main-plate 8 with all parts it carries. The plates 36 and 36 form two sets, and the plates of the set. 86 rise when, those of the set 86 remain stationary, and reversely, in

consequence whereof the grains cannot move .olinedtowards each ot-her (Fig. 1) between the upper plate 34 and the lower or intermediate plate or bottom 39 39 two sets of longitudinal walls 40 41 42 and 40 41 42' are arranged which are of different lengths (Fig, and form parallel channels 43 44 45 and 43 44 45, at the ends ofwhich the grains get into chambers 47 48, 49 and .47 48 49 50 formed by vertical cross-walls 51 52 53 54 and 51 52 53. 54, which are stepped differently at their upper edges. From the chambers 47-5O and 47-50/ the grains get onto. the table 12 through outlet branches. 55 discharging each into a separate channel 12 of the said table. here the channels 43-45 and 43,-45 commence, the-re the walls 40-.42 and 4042" are provided with horizontally movable flaps 5,6 and 5 6 (Fig. 4) secured to short vertical axles 57 and 57 provided with handles 58 and 5 8, as well as with nuts. 59, and 59 which can be turned on correspondingly threaded parts of said axles and by whichthe flaps can be secured in the position to which they have. been adjusted for shutting said channels partly or wholly, as desired or required.

The manner of. operation of the machine is as, follows:

The substance or material to be sorted is fed onto. the plate '34 where it commences to travel in the two directions from the middle of the plate to the ends thereof by reason, firstly, of the rocking motion of the box as caused by the mechanical means described, secondly, of the provision of the triangular ledges 35 35, and thirdly of the flaps 3,6 36. While thus travelling, a presorting takes. place in this way that the light grains andthe foreign impurities collee-t upon. the heavy grains. The flaps distribute the light grains and the foreign impurities completely uniformly over theentire breadth of the box, As the flaps of the two sets are opened and closed alternately, they let pass in intervals a certain amount of the grainseto, i. e. the heav grains, as well as. the light ones etc. in a height equal over the entire vbreadth. The pro-sorted grains fall through the passages 38 38 onto the intermediate bottom 39 3 9 which is sub divided intochannels and chambers as above described. As each channel has the same breadth and. as the grain falling down from the plate 34 onto the-bottom 39 39 has an grains and in consequence thereof also all. chambers receive equal amounts of grains, equal with respect to quantity, as well as to weight, and these equal amounts then get separated from each other through the branches into the channels 12" on the table 12.

If only a part of the feed box be used, one or more of the flaps 56 56 is, or are closed.

It has already been stated that the table 12 can be adjusted to several degrees of obliquity, the obliquity lying at right angles to the rocking motion of the suspended system. Any change or variation in the degree of obliquity can be effected in a simple manner, as well as quickly and accurately,

by means of? the eccentric 21 (or eccentrics,

if there are two, one on one crossbeam, the other on the other cross-beam, as described) which can be actuated by the hand-lever 25 in such a manner that the axle or journal 23 is lifted or lowered together with the table. But prior thereto the hand-wheel 27 must be loosened by screwing it off the hub 22 on the threaded pivot 26, which is true also of the hand-wheel 30 of the fixing device located at the other end of the crossbeam, as also described. This having been done, the hand-lever 25 is turned appropriately so as to turn the eccentric in one or the other direction, according as the obliquity of the table is to be increased or decreased, and then the nut'forming hubs of the handwheel 1 are again drawn home as to se cure the parts in their new position.

The means for rocking the table 12 have already been fully described and their man nor of operation will be clear to every expert without further details.

()wingto the mcking system being sus pended by means of the pendulums 2, the grains thrown against the battle-members 35 35 are subjected to a transporting component not only in the direction to the ends of the plate 2A, but also in upward direction whereby the sorting process is influenced in a f avoin'able manner.

Further adwintages afforded. by suspending the table by the pGIKlllllll'llf-i consist therein that the machine operates free fronii shocks so that the foundation is not subject-- ed to a COI'IGSPOIICllIIg strain and the buildings in which. such machines are housed are not caused to vibrate or shake. Besides, the rocked masses can be slight, and fly-Wheels may be either completely dispensed. with or small ones will. do. llie consumption of power is comparatively slight. Adjusting or varying the number of revolutions can be effected simply by shifting the belt laterally. lVIanipulating the hand-wheels can be effected while the machine is in operation.

Finally, owing to the feed-device being devised in the particular-manner shown and described, the output, especially secd-grain,

is remarkably uniform, the corns or grains being of perfectly like quality.
